Problems solved by technology

[0009] When two different units are located in separate gaps in the engine compartment, there is an additional disadvantage due to the need to extend the ducts connecting the two units
The two devices and these pipes connecting them occupy limited available space which further complicates engine assembly and repair

Embodiment Construction

[0046]According to a first inventive aspect, the invention concerns a device for heat exchange that can be integrated in an engine block. In all embodiments, heat will be performed between the hot gas (i.e. the recirculated gas from the exhaust duct of the internal combustion engine) and the liquid coolant (i.e. the liquid coolant circulating through the interior of the engine block (E)) exchange.

[0047] According to all the embodiments to be described, the exchanging means are configured to be housed in a chamber (C) provided in the engine block (E). Liquid coolant is also envisaged to flow in this chamber (C) in order to dissipate the heat dissipated by the hot gas through the heat exchange means.

[0048] The same engine block (E) also has openings (R) for receiving recirculated gas after it has been cooled by the device.

[0049] figure 1 Shown is a longitudinal section of the first embodiment together with a schematic representation of the engine block (E) and the ca...

Abstract

The present invention relates to a heat exchange device suitable for cooling recirculated exhaust gases in an EGR (Exhaust Gas Recirculation) system. The invention is characterized by a configuration which allows integrating the heat exchanger in a cavity of the engine block of an internal combustion engine with fluid communication with the liquid coolant.

Description

technical field [0001] The invention relates to a heat exchange device suitable for cooling recirculated exhaust gas in an EGR (Exhaust Gas Recirculation) system. [0002] The invention is characterized by a configuration that allows the integration of a heat exchanger in a cavity of the engine block of an internal combustion engine in fluid communication with a liquid coolant. [0003] The invention has the effect of protecting the environment. Background technique [0004] One of the fields of technology that is undergoing intensive development is that of systems for reducing polluting emissions in internal combustion engines. [0005] Specifically, EGR systems recirculate a portion of the exhaust gas by reintroducing the gas into the intake to reduce the amount of oxygen entering the combustion chamber, and thus reduce nitrogen oxide emissions. [0006] The recirculated gas must be pre-treated to prevent it from having dust particles and to prevent its temperature from ...
